Remove emscripten build.
Prefer using custom toolchain with amalgmated build.

- Let abstract types define a hash function and comparison/equality semantics. This lets
|
||||
abstract types much better represent value types. This adds more fields to abstract types, which
|
||||
will generate warnings when compiled against other versions.
|
||||
- Remove Emscripten build. Instead, use the amalgamated source code with a custom toolchain.
|

- Update documentation.

### Emscripten
|
||||
|
||||
To build janet for the web via [Emscripten](https://kripken.github.io/emscripten-site/), make sure you
|
||||
have `emcc` installed and on your path. On a linux or macOS system, use `make emscripten` to build
|
||||
`janet.js` and `janet.wasm` - both are needed to run janet in a browser or in node.
|
||||
The JavaScript build is what runs the repl on the main website,
|
||||
but really serves mainly as a proof of concept. Janet will run slower in a browser.
|
||||
Building with emscripten on windows is currently unsupported.
